The construction industry is being revolutionised quickly. "Almost every advancement in construction is small enough for a man to carry" - https://austinvernon.site/blog/construction.html https://austinvernon.site/blog/construction.html So if Katerra wanted revolutionary construction that jumps even quicker than this ongoing well documented advancement, Elon Musk style from the ground up, they need a reason why their product would work contrary to what anyone can see. They never gave one, so I don't see why it would have worked. Prefab needs a prefab factory in every city. And think of how limiting in design that would be. Kick ass screws need one factory in the world. And the fact people get militant about things like Square-Drive screws means screws will continue to be pushed evolutionarily. Who knows if the Phillips head can be upended but we are at a time in history that we can find out.
